Chiusella Valley
The mines of Traversella (TO)

The Valchiusella occupies the upper Canavese to Ivrea North-West and is crossed by the Chiusella River tributary of the Dora Baltea.

Located in Valchiusella, Traversella is a picturesque village which is about 60 km from Turin (Turin).

Excellent base camp for excursions of alpine tours and busy resort.

The territory of the municipality of Traversella is visited by experts and fans of Mineralogy.

A good part of the story of the charming Traversella is linked to the mines.

These deposits were exploited for centuries, represented wealth, work, and pain to the inhabitants of the Valley.

The exploitation of the mines represented since the middle ages an important economic resource for the local community.

The cultivation of the minerals in the past centuries was made by digging tunnels without following a specific order with the consequence of collapses and losses of lives.

The most flourishing period of mining activities goes back to that self sufficient.

Global economic competition of raw materials, lower costs of extraction, resulted in the closure of Traversella mines in the early 70 despite mineral reserves are considered.

Alpine mountain range formed about 50 million years ago.

Under the Valchiusella, about thirty million years ago, a volcano trying to rise to the surface with his molten magma.

Volcanoes that fail to reach the surface are called (PLUTONS), and rocks that form when they solidify are called (intrusive rocks).

The Pluto was forced to cool without being able to vent his strength, forming the mountain now called Betogne, and its heat melted and modified the rocks all around.

After millions of years, the erosion of the rocks brought to light the Pluto solidified.

This magma solidified millions of years today is extracted from the quarries of Traversella, Brosso, and Vico and is called diorite.

During the eruption went up along with the underground magma minerals that settled in rich strands arranged around Mount Betogne, and in particular in Brosso and Traversella.

The author offers over twenty years of personal knowledge of these places offer different photographic reports and years of mineralogical research.

At the beginning of the new Millennium my dear friend Arrigo touch, former miner and keeper of Traversella mines, he left, leaving me a great void.

The passion for mineralogy in these places was then replaced by great friendship for a character rich in values and capable of transmitting large teachings, when I went in the mines of Traversella said simply: '' I go by Arrigo '' the mines went into the background.

Arrigo, at the beginning of the 90, let me make photographic documentations in establishments of Traversella mine a little less than twenty years from the closing of mines.

His research directions in landfills and Fateh outcropping outside galleries were instrumental, as well as indications on the diorite quarries and Montaju deposits in the Valley of the Bersella and Included.

The entrance to the galleries of the mine was strictly forbidden.

Thanks to the process of valorisation of Traversella mines currently underway by the Gruppo Mineralogico Paleontologico of Valchiusella (G.M.V.) and the excellent attention of the municipality of Traversella revolt in the process, the author could make several photo reports within the various levels of the tunnels of mines and at the headquarters of the present mineralogical museum and mine equipment Traversella.

The Museum is home to the former silos stationary of the extracted material, is thematic in nature, and is designed to preserve and exhibit artifacts and objects that testify to the important mining and wealth spent of mineralogical samples Traversella mine.

The author received a gift from G.M.V. a sampling of mineral discoveries made during their years of activity since 2000 following the favorable response of the municipality of Traversella has set up a working group/research, consisting of local and external volunteers.
